9800GX2 Airflow?

post #1 of 10
Thread Starter 
Just wondering about the airflow of the 9800GX2 stock cooler, is it the same as previous cards, where the air is pushed through the back out of the pci slots?

On my case I can position fans on the side as well as front, I'm wondering if I should have them pushing air towards the card or away. If it's dumping heat inside the case then it might make sense to have it push air instead.

Any help appreciated.

I think the air going towards the card should be fine. Not exactly sure since I am not a 9800GX2 owner.

Being a logical nerd, I'd be willing to bet that the air is pushed out through the slot instead of dumped into the case.

I think it does a little of both, pushing air out side the case and inside the case. I got one of those Vantec PCI-slot coolers and that helps, specially with the expansion slot plate between the cooler and the GPU removed.

I am finding that the cooling system on the GX2 is great, I ran all the way through 3dmark at stock clocks and 80% fan and the highest temp was 59C!

Also when I play CS:S it barely gets over 50C. I reckon it would get hotter if I didnt have any CPU limit but its still running way cooler than my G80 GTS...

So, what's the direction of the air flow?

lol, I think his intention was to brag rather than to actually answer the question.

It seems to be as people suggested though, the air is pushed outside the back of the case. Curiously there is actually holes in the pcb and grills on the outside that allow heat to escape. The completely metal cooler also helps because it gets very warm after a while which is why I recommend having an additional fan over it.

Yeah, that was obvious. But thanks for clearing that up. I never could've figured it out without you.

Not at all, sorry if it seemed that way. These cards get a lot of bad press about being stupidly hot when they just aren't, the standard 45% fan speed doesn't help.

All the Air is exhausted from the PCI plate, however the metal case gets hot so it radiats heat into the case, the airflow is out though.

45% stock fan speed? Wow. Even I know better than that (I'm pointing my finger at nVidia).

Hmm, maybe we'll be seeing a lot of people using water cooling on these newer graphics cards.
